## Detailed Description

Build an interface from a UI definition description.

This object represents an `instantiation' of an UI definition description. When one of these objects is created, the XML file is read, and the interface is created. The Gtk::Builder object then provides an interface for accessing the widgets in the interface by the names assigned to them inside the UI description.

| protected

Glib::RefPtr<Glib::Object> Gtk::Builder::get_object | ( | const Glib::ustring & | name | ) |

Gets the object named name.

Note that this function does not increment the reference count of the returned object.

Since gtkmm 2.12:

Parameters

  name | Name of object to get.

Returns
  The object named name or `nullptr` if it could not be found in the object tree.

Glib::ustring Gtk::Builder::get_translation_domain | ( |  | ) | const

Gets the translation domain of builder.

Since gtkmm 2.12:

Returns
  The translation domain. This string is owned by the builder object and must not be modified or freed.

static GType Gtk::Builder::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

template <class T_Widget >

void Gtk::Builder::get_widget | ( | const Glib::ustring & | name,
|  | T_Widget *& | widget
| ) |  |
| inline

Get a widget from the Builder file.

For instance:

Gtk::Table* pTable = 0;
refXml->get_widget("mytable", pTable);

This method prints a warning message to the console if the widget doesn't exist or has the wrong type, so you don't need to check that manually.

Note that you are responsible for deleting top-level widgets (windows and dialogs) instantiated by the Builder object. Other widgets are instantiated as managed so they will be deleted automatically if you add them to a container widget.

Parameters

  name | The name of the widget.

Return values

  widget | A pointer to the widget, or `0` on failure.

Gtk::Widget* Gtk::Builder::get_widget_checked | ( | const Glib::ustring & | name,
|  | GType | type
| ) |  |
| protected

template <class T_Widget >

void Gtk::Builder::get_widget_derived | ( | const Glib::ustring & | name,
|  | T_Widget *& | widget
| ) |  |
| inline

This provides a pointer to a widget whose details are specified in the GtkBuilder file, but which is implemented by your own derived class.

Your class must have a constructor like so:

DerivedDialog::DerivedDialog(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& refBuilder)
: Gtk::Dialog(cobject) //Calls the base class constructor

For instance:

Gtk::DerivedBox* pBox = 0;
refXml->get_widget_derived("mybox", pBox);

Parameters

  name | The name of the widget.

Return values

  widget | A pointer to the widget, or `0` on failure.

GtkBuilder* Gtk::Builder::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GtkBuilder* Gtk::Builder::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GtkBuilder* Gtk::Builder::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Builder& Gtk::Builder::operator= | ( | Builder&& | src | ) |
| noexcept

Glib::PropertyProxy< Glib::ustring > Gtk::Builder::property_translation_domain | ( |  | ) |

The translation domain used by gettext.

Glib::PropertyProxy_ReadOnly< Glib::ustring > Gtk::Builder::property_translation_domain | ( |  | ) | const

The translation domain used by gettext.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::Builder::set_translation_domain | ( | const Glib::ustring & | domain | ) |

Sets the translation domain of builder.
